Afghanite: A New Silicate‐Matrix Reference Material for In Situ Halogen and Sulfur Microanalysis

Geostandards and Geoanalytical Research, EarlyView.
Key Points A new silicate matrix reference material for in situ chlorine and sulfur determination. Homogeneous across all measured elements. No matrix effects for Cl when calibrating silicate matrices, in contrast to scapolite, which causes systematic Cl overestimation of up to 13%.

SC‐550: A Sintered Calcite Reference Material for In Situ U‐Pb Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points New calcite reference material (SC‐550) produced by high‐temperature and high‐pressure sintering of nano‐particulate powder from a microbial limestone. Homogeneous U content (2.3 ± 0.4 μg g‐1) and U‐Pb isotope ratios (< 0.6% RSD for 207Pb/206Pb; < 3% RSD for 238U/206Pb).

Anaerobic Attenuation of Diisopropyl Ether (DIPE) in Groundwater: Kinetics and Implications for Monitored Natural Attenuation

Groundwater Monitoring &Remediation, EarlyView.
Abstract Diisopropyl ether (DIPE) is a branched ether used as a solvent, extractant, and gasoline additive. While aerobic biodegradation of DIPE has been documented, attenuation under anaerobic conditions (typical of groundwater impacted by petroleum hydrocarbons and fuel oxygenates) remains poorly constrained.

Delivering Sulfate to LNAPL Body for Enhanced Source Zone Depletion (ESZD)

Groundwater Monitoring &Remediation, EarlyView.
Abstract This field pilot study evaluates the feasibility of applying sulfate to a light non‐aqueous phase liquid (LNAPL) body for achieving enhanced source zone depletion (ESZD) at a refinery site. Two rounds of gypsum land application (GLA) delivered sulfate to an 8000 ft2 area encompassing LNAPL‐containing monitoring wells MW‐2 and MW‐3, while MW‐1 ...
